| Abstract: | The methanolic extract of geranium, Pelargonium graveolens L’ Herit. ex Ait.
leaves was used to impart antimicrobial and aroma finishing to the cotton
fabric. The extract was microencapsulated using two different methods namely
coacervation-spray drying and direct spray drying techniques. The results
indicated that the direct spray drying method produced smaller capsules
with 5  size in powder form and 12.5 in aqueous form compared to the 7.5 and 17.5 respective
capsule sizes produced by coacervation-spray drying method. The
microencapsulated geranium leaves extract treated cotton fabrics showed
antimicrobial efficacy against both Staphylococcus
aureus and Escherichia coli.
However, the Gram positive Staphylococcus
aureus was more susceptible to geranium extract compared to Escherichia coli. The microcapsule
treated fabric retained
50-60% aroma after 10 washes compared to the nil retention property of pure
geranium extract treated fabric. |
